 ## Summary
 
-Investigated routing optimization for agentic workloads on PD-combined serving. Found that **session-sticky routing with load-aware override** achieves the best balance of KV cache reuse (APC) and request latency.
+Investigated routing optimization and selective PD offloading for agentic workloads. Found that **PD-combined with hybrid routing** (session-sticky + load-aware override) is strictly optimal for single-machine serving. All forms of KV transfer (full PD-sep, selective offload) add overhead that exceeds the isolation benefit.
 
-**Key result**: +4.7pp APC improvement (44.7% → 49.4%) with zero latency regression.
+**Key results**:
+- Hybrid routing: +4.7pp APC (44.7% → 49.4%) with zero latency regression
+- Adaptive v2 (selective Mooncake offload for HEAVY requests): +36% TTFT, +35% E2E — worse
+- **Definitive conclusion: on single-machine 8 GPU, no KV transfer scheme helps agentic workloads**
